For a while I had a full sized keyboard stored in the back of the jeep that I would pull out when needed. With my latest install i'm going the rii mini route. I was going to get the Bluetooth version but I was under the impression that it wouldn't work until window and the Bluetooth driver was loaded. So getting into the BIOS of the carp would be tricky. I could be wrong about that though.

My Mouse and KB

I use the SMK Link Ultar Mini Mouse and the 80-key Mini Flexable keyboard. They are perfect for my truckputer setup. the KB rolls up and fits into a nice small clear plastic tube that it comes with and fits right inside my glove box. the mouse is SWEET!!!!! its wireless, USB, and rechargable. When im driving i just keep it charging all the time. it uses a magnet to attach itself to the USB end to charge. below are some pics of both. also links if you want to buy them!

I use the Rii Mini Keyboard (also called ProMini). It's small but durable, has a backlight, and has a built-in touchpad. The only problem is that it doesn't have F9-F12 keys. Other than that, it works wonders.

Which type of batteries is inside your keyboard and how long will those batteries lasts?

I just picked this one up this evening to try out. So far on my laptop it works like a breeze. No setup at all, plug in the 2.4Ghz dongle and away you go. It's made for the PS3, works perfect on the pc, backlit, and cheap (feels a little cheap but it's not like I'll be using it for self defense) - $29 at wal-mart

:edit: looks like Windows 7 detects all 3 devices. A mediacenter keyboard, a game controller, and a mouse. Under the Devices and Printers control panel you can even customize settings for each. The mouse doesn't actually work, but the game controller does. The POV hat as well as 13 buttons function. Actually kinda cool for a $30 wal-mart remote. Have to see how it does in the car though.

^^^^ I have the version of this keyboard sold here on MP3car. The back light is nice but I find the hard plastic case and hard to push buttons very hard to type on. And the keyboard layout is bizarre IMO. It is rechargeable and the battery life is excellent though.
I would make a different choice if I was to replace it.

At the top is broken Umax illuminated keyboard. In the middle is iOne wireless keyboard - this is my favorite, but have horrible power consumption. The smallest keyboard at the bottom is my current keyboard. It sucks writing on it.

On this picture is keyboard laying on opened foldable doors of my center console

Here is shot of the foldables doors closed.
And tomorrow I become the new one.
